no stereo mix Realtek

[Cristiano25]

Good evening to you all. In my HP laptop 28K70EA stereo mix is missing; I have tried various solutions (for example, driver update but not supported). I'm an italian teacher; I need it because during remote lessons to school students (at present in Italy 90% of lessons are by remote causa Covid 19) 
I usually show videos ( for example from YouTube, etc, ) but without stereo mixer they don't hear the audio of the videos on my pc.
Windows 10 edition: Windows 10 Home 20H2 
Build operating system: 19042.867
Realtek driver audio version: 6.0.8924.1 
Also there is no HP Audio Control software.
How can this be solved? Thanks

P.S. I own another HP laptop,15-da0xxx,in which stereo mixing is present; the audio driver version is 6.0.9025.1 
Here's HP Audio Control software.

Ok now but why is stereo mix missing?

[KrazyToad]

This seems to be part of the latest update. The Stereo mix feature must have been removed by the manufacturer

Is there an alternative? I am a teacher and I need to have my pupils listen to the audio of a video on my PC or DVD.

You could try using 3rd party Apps

Which third-party apps can you recommend to me?

Are updated Realtek drivers available for download from the manufacturer's website? Or updates from HP to fix this soon?
